From b01da9f130adbf69cfbad2a65f1327f1382bf4ae Mon Sep 17 00:00:00 2001 From: David Daney Date: Thu, 5 Jul 2012 18:12:38 +0200 Subject: MIPS: Prune some target specific code out of prom.c This code is not common enough to be in a shared file. It is also not used by any existing boards, so just remove it. [ralf@linux-mips.org: Dropped removal of irq_create_of_mapping which was already removed by abd2363f6a5f1030b935e0bdc15cf917313b3b10 [irq_domain/mips: Allow irq_domain on MIPS]. Moved device_tree_init() and dependencies to its sole user, the XLP code.] Signed-off-by: David Daney Cc: linux-mips@linux-mips.org Cc: devicetree-discuss@lists.ozlabs.org Cc: grant.likely@secretlab.ca Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/2946/ Signed-off-by: Ralf Baechle --- arch/mips/netlogic/xlp/of.c | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 arch/mips/netlogic/xlp/of.c (limited to 'arch/mips/netlogic/xlp/of.c') diff --git a/arch/mips/netlogic/xlp/of.c b/arch/mips/netlogic/xlp/of.c new file mode 100644 index 00000000000..8e3921c0c20 --- /dev/null +++ b/arch/mips/netlogic/xlp/of.c @@ -0,0 +1,34 @@ +#include +#include +#include +#include +#include + +static int __init reserve_mem_mach(unsigned long addr, unsigned long size) +{ + return reserve_bootmem(addr, size, BOOTMEM_DEFAULT); +} + +void __init free_mem_mach(unsigned long addr, unsigned long size) +{ + return free_bootmem(addr, size); +} + +void __init device_tree_init(void) +{ + unsigned long base, size; + + if (!initial_boot_params) + return; + + base = virt_to_phys((void *)initial_boot_params); + size = be32_to_cpu(initial_boot_params->totalsize); + + /* Before we do anything, lets reserve the dt blob */ + reserve_mem_mach(base, size); + + unflatten_device_tree(); + + /* free the space reserved for the dt blob */ + free_mem_mach(base, size); +} -- cgit v1.2.3-70-g09d2
